US 6 – Sixth Avenue will be closed from Sheridan to I-25, Federal down to one lane

Major work on Sixth Avenue -US 6 begins Friday, Feb. 7, with a full weekend closure of US 6 from I-25 to Sheridan Boulevard. The highway will be closed starting at 9 p.m. Friday until 5 a.m. Monday, Feb. 10.

“This project will bring not only needed transportation improvements to west Denver, but it offers the opportunity to help connect neighborhoods on both sides of the US 6 corridor,” said Denver City Councilman Paul Lopez.

The $98 million project will replace six obsolete bridges on US 6 between Knox Court and I-25, improve traffic movements in the I-25 and US 6 interchange and enhance driver safety by eliminating several traffic weave movements along US 6 between Federal Boulevard and I-25.

“We are very excited to get this project started,” said Kevin Sullivan, CDOT Project Director. “These critical improvements have been a long time in the making and will make the roadways much safer and more efficient for local residents and commuters alike.”

During the weekend closure, crews will work day and night to take down the Knox Court bridge, remove a portion of the Federal Boulevard bridge and relocate an overhead power line; activities that would each require separate highway closures. Crews will also remove about 7,000 feet of center median barrier and put temporary barrier in place to shift traffic to the south side of the highway. It would take about 20 nights to do this work if it weren’t done during this weekend closure.

During the closure of US 6, east and westbound through traffic can use US 285, I-70 or C-470, while local traffic can use Alameda or Colfax Avenues as detour routes.

When the highway reopens Monday morning, travel lanes will be narrowed and shifted to the south, so motorists should drive with care. The following closures will also still be in place:

The Knox Court bridge over US 6 will be closed for about three months for reconstruction.

The Lowell Boulevard on-ramp to eastbound US 6 and the westbound US 6 off-ramp to Lowell will be closed for about three months while this bridge is rebuilt.

The Bryant Street on and off-ramps will be closed for about one year to build the collector-distributor roads on both sides of US 6.

The Federal Boulevard bridge over US 6 will be reduced to two lanes in each direction and the eastbound US 6 off-ramp to Federal Boulevard will be reduced to one lane.

The US 6 Bridges Design-Build Project involves improvements along 6th Avenue from approximately Knox Court on the west through the BNSF railroad track bridge just east of I-25. The project, which was part of the I-25 Valley Highway FEIS completed in 2006, includes building new bridges over Bryant Street, the South Platte River, BNSF railroad tracks, I-25, and over US 6 at Federal Boulevard and Knox Court, as well as improvements to Barnum Parks and a realigned off-ramp from northbound I-25 to westbound US 6.
